New photos of Khandalyce Pearce, whose remains were dumped in a suitcase on the side of a South Australian highway, have been found on the Facebook page of Adelaide woman Hazel Passmore.
Police believe the two-year-old and her mother, Karlie Pearce-Stevenson, were murdered.
Ms Pearce-Stevenson’s remains were found in the Belanglo Forest in NSW five years ago, while her daughter’s bones were found in South Australia’s Murray Mallee in July.
Daniel Holdom, 41, from New South Wales has faced court charged with Ms Pearce-Stevenson’s murder.
Police sources told the ABC’s 7.30 program Holdom was involved in a car accident in September 2008 that left his then-girlfriend in a wheelchair.
His girlfriend’s two young children were killed in the accident.
Police sources also said they believed Holdom’s then-girlfriend was the same woman who impersonated Ms Pearce-Stevenson in 2010.
On Tuesday police alleged a woman in a wheelchair posed as Ms Pearce-Stevenson during a bank visit in Adelaide in 2010 and at Centrelink later that same year.
Media outlets are reporting Ms Passmore is being interviewed by police, but police have declined to comment.
A number of images of Khandalyce were uploaded to Ms Passmore’s Facebook account in 2008.
On Tuesday, police alleged Karlie’s bank account was accessed hundreds of times over the years to withdraw almost $100,000 and her phone was used to contact family to make it look like she was still alive.
New South Wales Police told the media Ms Pearce-Stevenson was killed in 2008, between December 14 and 15.
Police believe Khandalyce was killed in a different location to her mother and at a later date.
No charges in relation to Khandalyce’s alleged murder have been made.
